My officemate had a credit card debt that has gone unpaid for several months. She changed her cellphone number to evade collection calls and has moved to another home. Since she was a newly-hired employee, the credit card company doesn't know her current office landline. She thought that she had successfully avoided collection harassment. To her chagrin, however, the credit card company has made a post on her Facebook wall about her unpaid debts. Since she doesn't access her FB account on regular basis, the post has been on her wall unknowingly for a few days. As far as I know, such collection tactics are not allowed. But since she was also negligent on her obligation to pay, can she actually file a legal case against the credit card company for harassment?
